Which of the following statement(s) is/are true regarding biogeochemical cycle in the ocean?

Your answerSelect all correct options. You can choose more than one.

Shutdown of the biological pump in the ocean would have resulted in higher CO₂ concentration in the atmosphere compared to present-day.

If atmospheric CO₂ concentration increases, solubility pump would lead to a decrease in dissolved inorganic carbon in the ocean.

All carbon sequestered by marine photosynthesis settles down on the ocean floor as organic matter.

Calcification (the process of making shells and skeletons) by marine organisms in the surface ocean layer would lead to an increase in the surface ocean CO₂.
